ABSTRACT Introduction Unicompartmental knee arthroplasty (UKA) is a treatment option in patients with unicompartmental degenerative disease. Compared to total knee arthroplasty (TKA), the advantages of UKA include accelerated recovery and cruciate ligament retention. These advantages, along with emerging evidence that mild patellofemoral joint osteoarthritis does not compromise results of UKA have encouraged expansion of the indications for UKA. Symptomatic lateral patellofemoral joint degenerative disease is a common cause of UKA revision. Partial lateral patellar facetectomy can provide relief from symptoms of lateral patellofemoral degenerative disease. We hypothesize that simultaneous UKA and lateral patellar facetectomy provides durable pain relief and functional improvement in a patient population with degenerative disease of one tibiofemoral compartment and the lateral patellofemoral joint. Materials and methods: Between 2004 and 2008, 11 lateral UKA's were performed in association with partial lateral patellar facetectomy in 11 female patients (mean age: 66.7 years) with degenerative changes in one tibiofemoral compartment and the lateral patellofemoral joint. Patients were followed clinically and radiographically for a mean of 5 years. Results No patient underwent revision surgery in the followup period. The mean international Knee Society (IKS) knee score improved from 64.9 ± 11.2 points preoperatively to 87.5 ± 12.6 points at final follow-up (p = 0.01). The mean IKS functional score improved from 65.9 ± 23.5 points preoperatively to 83.2 ± 23.3 points at final follow-up (p = 0.012). The mean Kujala score was 84.3 ± 13.5 points postoperatively. Progression of patellofemoral OA was observed in one patient. Conclusion Simultaneous UKA and partial lateral patellar facetectomy is a viable treatment option for symptomatic degenerative disease involving one tibiofemoral compartment and the lateral patellofemoral joint. This treatment approach may be a useful alternative to TKA or bicompartmental arthroplasty in a carefully selected patient population. Level of evidence Case series—Level IV.

Background: Use of mini-subvastus   approach for  total  knee  arthroplasty  (TKA )  in  obese  patients  is  still  debated . We had hypothesized in our  study published  in  July 2010 , that  obesity  should  not  be  considered  as  a  problem for  patients  undergoing  a  TKA  with  the  mini-subvastus  approach  as  the anatomy  of  the  quadriceps in  the  obese and  the  non-obese  patient population is  the  same. We present  a  mid-term  follow-up  study  of  the  same  set  of patients  with  an  average  follow  up  of  96 months.Materials and Methods: 97 obese patients (109 knees) 81 females + 16 males with mean age 64 years underwent TKA by mini-subvastus approach between January 2006 to July 2007. 16 patients (18 knees) were morbidly obese. Out of the total number of patients, 08 were lost in follow up and 01 died because of unrelated causes. Out of these 09 patients, two were operated for bilateral TKR. Thus, we have a midterm follow up results of 98 knees in 88 patients. Knee society and functional scores were used for patient evaluation and compared to their pre-operative and earlier follow up scores.Results: At our latest follow-up of 96 months the Knee Society Score and functional scores were 84(range 64-90) and 58(range 45-75) respectively. One morbidly obese lady had aseptic loosening of tibial component at 42 months which needed a revision.Conclusion: Our mid-term results show that the mini-subvastus approach can be  considered  for TKA in obese and morbidly obese patient population with outcomes comparable to standard surgical approach.Keywords:  Mini-subvastus approach, Total knee arthroplasty ,Obesity

Technical Considerations

ABSTRACT Unicompartmental knee arthroplasty (UKA) is now well-established as a treatment option for isolated compartment osteoarthritis (OA) of the knee. Improvements in surgical technique, instrumentation, component design, and rapid rehabilitation has resulted good long-term survivorship and in the wider acceptance for UKA. The experiences from several centers have been key in the education of surgeons with regards to patient selection, technical considerations, and importantly avoiding common pitfalls can lead to early failure of the components. A younger patient may require revision in their lifetime, but modern UKA design allows this to be performed with minimal surgical difficulties and with good outcome.

A Performance

The convenience of bedside percutaneous tracheostomy (PT) is growing in popularity. Some centers are placing PTs without the assistance of bronchoscopy. The study objective was to identify operative and perioperative problems with PT placement and to identify potential problems with bronchoscopy-free placement. All operative and perioperative events were prospectively recorded as a performance improvement project at our institution while performing bronchoscopic-assisted bedside PTs. One hundred eighty-three patients underwent PT placement, all with the assistance of a bronchoscope. Although most PT was performed without incident, some of the complications can be severe. The majority of difficulties can be prevented with bronchoscopic assistance. An unexpected procedural difficulty that has not been previously reported is the dilatational difficulty in the younger patient population. Some of these patients required an additional tracheal incision with a scalpel. This may be from a healthy pretracheal fascia and/or musculature.

Association of partial nephrectomy with a long-term survival advantage in patients between age 20 and 44 with renal cell carcinomas ≤ 4 cm: An analysis of the SEER database.

Chi Square Analysis

408 Background: PN decreases the risk of developing chronic kidney disease as opposed to RN. While prior studies have demonstrated the survival advantage of PN in older patients, they have been criticized by selection bias in procedure selection due to comorbidities. We hypothesized that the long-standing effects of renal preservation would manifest in a survival advantage of a younger patient population, where this selection bias is minimized. Methods: The SEER 18-registries database was queried for patients between the ages of 20 to 44 that were surgically treated with either PN or RN for RCC between 1993 and 2003. We have excluded patients with metastatic or locally advanced disease and included patients with localized tumors ≤4 cm with known grade. The histologies selected were clear cell, papillary, chromophobe, sarcomatoid, collecting duct, and renal cell. The final cohort consisted of 222 and 494 subjects treated with PN and RN respectively. Chi-square analysis compared tumor variables and patient characteristics. Cancer-specific and overall survival rates were compared at 5 and 10 years using Kaplan-Meier analyses. Results: There were no differences between patients treated by PN or RN in demographics or tumor characteristics. Additionally, there was no difference in cancer-specific survival between the two groups at 5 or 10 years (p= 0.34 and p = 0.1 respectively). While there was no difference in 5-year overall survival (98.2% vs. 95.5%, p = 0.07), the patients treated with PN had an advantage in 10-year overall survival compared to patients treated with RN (94% vs. 89.7%, p = 0.025). Conclusions: Present SEER analyses demonstrate that when compared to RN, PN results in improved overall survival in patients treated for small, localized RCC. As expected, the survival advantage is observed late and supports the importance of long-term renal functional preservation. The present study of a younger patient population allows for minimizing selection bias in choosing surgical procedure due to comorbidities and provides further support for maximal renal preservation in patients with a life expectancy of 10 years or more.
